Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances concerning the regulation of chromosome segregation during cell division by means of centromeres and kinetochores. The authors cover both state-of-the-art techniques and a range of species and model systems, shedding new light on the molecular mechanisms controlling the transmission of genetic material between cell divisions and from parent to offspring. The chapters cover five major areas related to the current study of centromeres and kinetochores: 1) their genetic and epigenetic features, 2) key breakthroughs at the molecular, proteomic, imaging and biochemical level, 3) the constitutive centromere proteins, 4) the role of centromere proteins in the physical process of chromosome segregation and its careful orchestration through elaborate regulation, and 5) intersections with reproductive biology, human health and disease, as well as chromosome evolution. The book offers an informative and provocative guide for newcomers as well as those already acquainted with the field.
Download or read book The Kinetochore written by Peter De Wulf and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetochores orchestrate the faithful transmission of chromosomes from one generation to the next. Kinetochores were first depicted over 100 years ago, but kinetochore research has progressed by leaps and bounds since the first description of their constituent DNA and proteins in the 1980s. “The Kinetochore: from Molecular Discoveries to Cancer Therapy” presents a thorough up-to-date analysis of kinetochore and centromere composition, formation, regulation, and activity, both in mitosis and meiosis, in humans and “model” eukaryotic species, and at natural and mutant neocentromeres. Recently initiated translational research on kinetochores is also discussed as kinetochores are being mined as a very rich target for the next generations of anti-cancer drugs.

Download or read book The Centromere written by K. H. Andy Choo and published by Oxford University Press, USA. This book was released on 1997 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centromere is an essential structure on all eukaryotic chromosomes that allows the equipartition of chromosomes during mitotic and meiotic cell divisions. Since its cytogenetic recognition as a constructed part of a chromosome many decades ago, great advances have been made in ourunderstanding of this intriguing structure, especially at the molecular level. This book brings together all available information on the centromere. It covers in details the DNA and protein components of this structure, and their individual functions, in species as diverse as budding and fissionyeasts, nematodes, Drosophila, mice, and humans; newly discovered roles of the centromere in marshalling "passenger" proteins; important emerging concepts such as latent centromeres and epigenetic factors; cytogenetic problems associated with centromere abnormalities; and practical application ofcentromere studies, such as in the construction of human artificial chromosomes for gene therapy. Supported by ample illustrations, the book is written with sufficient simplicity and detail to suit both specialist and non-specialist scholars. It is the first book on the subject

Download or read book Cells Molecules and Mechanisms written by Eric Wong and published by Axolotl Academic Publishing. This book was released on 2009 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Yet another cell and molecular biology book? At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology."--Open Textbook Library.
Download or read book Centromere written by Durdica Ugarkovic and published by Springer Science & Business Media. This book was released on 2009-06-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centromere is a chromosomal region that enables the accurate segregation of chromosomes during mitosis and meiosis. It holds sister chromatids together, and through its centromere DNA–protein complex known as the kinetochore binds spindle microtubules to bring about accurate chromosome movements. Despite this conserved function, centromeres exhibit dramatic difference in structure, size, and complexity. Extensive studies on centromeric DNA revealed its rapid evolution resulting often in significant difference even among closely related species. Such a plasticity of centromeric DNA could be explained by epigenetic c- trol of centromere function, which does not depend absolutely on primary DNA sequence. According to epigenetic centromere concept, which is thoroughly d- cussed by Tanya Panchenko and Ben Black in Chap. 1 of this book, centromere activation or inactivation might be caused by modifications of chromatin. Such acquired chromatin epigenetic modifications are then inherited from one cell di- sion to the next. Concerning centromere-specific chromatin modification, it is now evident that all centromeres contain a centromere specific histone H3 variant, CenH3, which replaces histone H3 in centromeric nucleosomes and provides a structural basis that epigenetically defines centromere and differentiates it from the surrounding chromatin. Recent insights into the CenH3 presented in this chapter add important mechanistic understanding of how centromere identity is initially established and subsequently maintained in every cell cycle.

Download or read book The Kinetochore written by Jack Houston and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During mitosis, chromosomes must connect to the microtubule mitotic spindle and divide equally into two new daughter cells. The molecular machinery that accomplishes this task is the kinetochore, which is built on the centromeres of chromosomes and attaches to the mitotic spindle. My dissertation work has focused on 1) How the centromere is specified, 2) How kinetochores control the amount of time a cell spends in mitosis, and 3) How the essential protein bub-1 is recruited to kinetochores. Centromeres are specified by the presence of the histone like protein CENP-A. However, in C. elegans the chaperone proteins that recruit CENP-A to chromatin are missing. We discovered that the N-terminal tail of CENP-A functions as a chaperone to promote its binding to KNL-2/MIS18BP1 and centromere deposition. Once the kinetochore is built upon the centromeres of chromosomes, it optimizes the amount of time the cell spends in mitosis to promote timely anaphase onset. Kinetochores control mitotic timing in part by regulating flux and de-phosphorylation of the APC/C co-activator CDC-20. Kinetochore localization of CDC-20 is mediated by the ABBA motif of BUB-1. We discovered that a PLK-1 docking site on BUB-1 was also required for CDC-20 recruitment, and that PLK-1 phosphorylates the ABBA motif of BUB-1 to promote CDC-20 kinetochore recruitment and proper mitotic timing. In order to regulate mitotic timing and execute its other functions, BUB-1 must localize to the kinetochore. The current model in the field is that BUB-1 binds to BUB-3 to bind with p-MELT motifs on KNL-1. However, BUB-1 and BUB-3 depletions have significantly different phenotypes in early embryos, and perturbing MELT phosphorylation or phospho-recognition does not prevent BUB-1 kinetochore recruitment. Instead, we discovered that the N-terminal TPR domain of BUB-1 is necessary for BUB-1 kinetochore recruitment, and sufficient to localize to kinetochores on its own.

Download or read book Cellular Organelles written by Edward Bittar and published by Elsevier. This book was released on 1995-12-08 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to provide a synopsis of present knowledge of the structure, organisation, and function of cellular organelles with an emphasis on the examination of important but unsolved problems, and the directions in which molecular and cell biology are moving. Though designed primarily to meet the needs of the first-year medical student, particularly in schools where the traditional curriculum has been partly or wholly replaced by a multi-disciplinary core curriculum, the mass of information made available here should prove useful to students of biochemistry, physiology, biology, bioengineering, dentistry, and nursing. It is not yet possible to give a complete account of the relations between the organelles of two compartments and of the mechanisms by which some degree of order is maintained in the cell as a whole. However, a new breed of scientists, known as molecular cell biologists, have already contributed in some measure to our understanding of several biological phenomena notably interorganelle communication. Take, for example, intracellular membrane transport: it can now be expressed in terms of the sorting, targeting, and transport of protein from the endoplasmic reticulum to another compartment. This volume contains the first ten chapters on the subject of organelles. The remaining four are in Volume 3, to which sections on organelle disorders and the extracellular matrix have been added.
